Rear Brake Rotor Size?

[dwallzee]

I'm upgrading my rear brakes to disc and want to use an aftermarket rotor. I've searched and searched and the only thing I've found is that the rear rotor is 268mm. Is this correct? Does anyone know what bikes come with a rotor this size? Thanks for The help.

Anyone have a stock one they can measure?

They are the same as the XS750-850 fronts and rears.

from an ebay 750 front ad.

10 9/16" = 268.288mm

These new chinese rotors seem like the right size.... would need to confirm all the dims but....

a PAIR drilled and 5.5mm thick that's not a bad price, for chinese...

here's a single that seems right, slotted not drilled.

That last one is for a LH mount, the slots are angled the other way, don't know if that really matters anyways.

On the slots, they would look funny if they were both the same, so they made a left and right. That way the slots went the same way. Both angle backward.
